石油产品和润滑剂 润滑脂的流变性能 用带锥/板的振荡流变仪测定含金属皂增稠剂的润滑脂的稠度

[中文适用范围]： 本文件规定了使用振荡流变仪通过剪切变形测定金属皂基润滑脂一致性的程序。本试验方法适用于新制备的和使用的润滑脂，其中仅含有少量的油脂，通常无法确定工作针入度。所确定的校准仅对金属皂基润滑脂有效，例如锂基、锂钙基以及锂-钙复合基润滑脂。本文件中所述的方法适用于按 ISO 6743-99 分类为 NLGI 级别 00、0、1、2 和 3 的润滑脂。 [外文原描述]： This document specifies a procedure to determine the consistency of a metal-saponified lubricating grease by an oscillatory rheometer. This test method is applicable for fresh, as well as used, lubricating greases where only small quantities of the grease are present and the worked penetration that is usually used cannot be determined due to the small quantity. The determined calibration is only valid for metal-saponified lubricating greases like lithium, lithium-calcium and, also, lithium- and calcium complex. The method described in this document is applicable for lubricating greases with NLGI grades 00, 0, 1, 2 and 3 according to ISO 6743-99.
